This invention relates to trucks.

An object of the invention is to provide trucks o f lightand'exceptionally ystrongconstruction, Which are particularly Well adapted for use in the transportation of materials between various departments of stores, mills, factories and the like, or in any other situation in which Ya light, strongtruckmay be useful.

Another object of the invention is to provide a: truck ofthis character made up of a. plurality of thin panels of composite construction, each of which vincludes a plurality of layers of Wood and sheet' metalsecured'together, With means for reinforcing andbinding such panels together to provide a truck body receptacle Whichmay be equipped with suitable rollers or Wheels.

In the use of trucks of this character the same are frequently bodily transported from place to place and. during suchv transportationit is important ythat the contents of the trucks be secured against vaccidentalfor uns.

authorizedremoval, ,and a further purpose of the present invention isfto provide a truck of this character including suitable doors made up offcomposite panels of the character above mentioned, together With suitablejournalsand journal bearings associatedlW-ith the doors and the truck Abody for s wingably mounting the doors on the'truck. y

A further object of theinvention is to provide means `for mounting the: doors Ain such manner that they Will""lie'flatlagainst the outer side Walls of the truck body whenl in open position, and when movedto position toy close the receptacle, .engage means provided adjacent they swinging aries of the doors Whichliniit the closing moveli'nent and properly support the doorslin-the desired closed'position.

A stillfurther object ofthe invention is to provide a` v composite door` panellV of the characterY mentioned?, in which portions thereof have beencut awayfto provide extensions at its corners,the y,sheet metal lof course, remaining in positiontoreinforce theextensionsotogether with ,half'zround stiffening strips. .of suitablehmaterial which are disposed along the. opposite faces of the edge of the panelend,projectalong the' extensions formed on the panel, the end' portions of suchnstripsand the ertteIlSonsr providing cylindrical journals adapted, toy Abey received in. suitable socketsor brackets ,on the truck on the line 4 4' ofy Fig. 3; and Fig. 5 is a. partial, sectional View. of the invention siniilar to Fig. 3, showing the door in open position.

contemplated by my invention is indicated generally by the letter A. Such truck comprisesIv a4 plurality of side panels10,an,d end panels 11, n each of said' panels preferably be- 7 0 1s a partial, sectional view ofthe invention 7,5 In the dra\vings,a truck of the character i l ing ofl a composite construction made up of a thin' Wood'sheet or core 12, having thin lsheets of sheet metal 13 and 14 secured to itsnopposite sidesas best shown in Figs. 3 yand 5, .thevsheet-metal being secured to the wood corebymeans ofa process described and claimed reissue Patent No. 14,849 dated September' 11,1917,the construction forming in eifectshe'et metal veneerevd panels of' greatstrength andv- 'durability'. well; `able to withstand1t11e hardI usage to which trucks of this ,y character are ygenerally sl-lbjected. The panels 10,*.andj1-1v are assembled in rectangular formation, .and provided with a suitable bottom,1 upon which is mounted rollers 1.5. [Such bottom isA preferably made up lofthe same material as the panels-l0 and 1 1, preferablyof aA plurality `of thicknesses of such material. Longitudinally extending bottomrrstrips 16, and transverse Ystrips 17. are provided to which: ythe bottomportions of the-panels l()V and -ll are secured. `Upriglit ystrips`1`8 extend along each corner 'ofthe truck body, to which the ends, of the panels 1,0 and 1l., are secured,4 such,uprightspreferably beingflinfthe form ofv angle barato which the] panels are riveted. The upper redges yofth'e'end panels 1l are provided with transversefbars 19,4`whfich` are preferably in the form of'y rounded coveringv strips', each provided With va groove 20 for the reception of the upper edge of the related panelv l1. rIhe covering strips 19 each preferably has an outer sheathing 21 of sheet metal, the inner edges of such-metal sheathing being turned into the groove 20 so as to securely hold the same in position, as best shown at 22 in Fig. 4. The end portionszof1 the cov-` ering strips 19 are vprovidedwvitl'i cut-outportions 28 on their inner sides, for a pur-y pose which ivill present-ly appear. yEach side panel 10 `is provided with4 a reinforcing strip 24 which is `secured thereto on the inner side; at itsupper edge by suitable rivets 25, the strips '2apreferably terminating soine little distance from the end Walls l1. The top edge of each ivall lO is outwardly bevelled as shown atv 2G.V Y

Each corner of the truck is provided with a metallic bracket 27, and as all of such brackets, except for their disposition, rare similar in construction and attachment, only one of the same is specifically ydescribed h erein. Each bracket?? is angular in form, and preferably U orchannel shaped in cross section, the angular portion 28 of such bracket being arranged, to tit snugly over the coverinr stri o 'i9 and sheathino` 2l such covering strip being secured to the panel l1, and the bracket to the panel ll land the covering strip, by means of rivets 29 extending through all of the parts. Y

The angular portion'SO of each bracket 27 has its inner Wall 3l ydisposed against the inner surface of the adjacent panel l0, and in the-space between the'end of the adjacent reinforcing strip 2&1- andthe panel 1l. The

opposite Wall 82 of the angular portion 3() of the bracket 27 is outvvardlyrspaced from they panel 10, as' clearly shown inFigs. 3 and 5, and in conjunctionftvith the bevelled portion'26 of the edge of the panel 10, and the cut-out portion 23 of the covering strip 19, provides a journal bearing 33, defined by the U portion of the bracket, the cut-,out portion 23 of the covering strip 19and'the curved bevelled edge 26 of the adj acent'side Wall 10. Similar bearings 33' are provided by each of the other brackets 27 at the respective corners of the truck body portion, such bearings being adapted for the reception of suitable journalsB/l, formed on the door members 35, which Willnow bede-` scribed.

v" Each of the door members 35 comprises a composite panel made up of layers of sheet metal, and fillers of suitable material, pref.- n j as the panels l() and 1l, and tliejo'urnalsM are provided by a novel arrangement ofthe parts. In forming such journals upon' the door members 35, stiifening strips 8 6 are disposed Vonopposite sides of the edge of the` door, such strips being preferablyhalf round 'in -cross section, and secured vto the panel by means of rivets 37, `the body portion of the door being cut out as shown at` 38, providing projections onthe door along which extend the end portions of the vstiftening strips 36, the end-"portions of such strips and the projecting bodj7 portions of the door, providing cylindrical journals Whichfit With-4 in the journal bearings, provided by the brackets 27, and the associated parts, thus mounting the doorfor 'swinging movement upon such journals.Y It shouldbe particularly observed that the projections onthe door in conjunction vvith the vstilfening strips' provide exceptionally' strong journals, since particularly observed that .thel journals I-.

formed on the doorV by the projections of the body portion thereof, together with the stiffening strips provide a strong andv durable door and journals', -iny Which the stillening strips brace the door andthe' journals, and such journal portion-s are also reinforced by the sheet of metal formingV part of the projecting portions ofthe body of thedoor.4 D y Vhile I'have herein shovvn 'and 'described v lwhat I novv consider the preferred manner. of carrying out the invention, the same'is merely illustrative andv I contemplate-all changes and modifications that come withinv the scoperof 'the claims appended hereto. x e yI claim: Y,
